Chapter 9 Major Positioning Control
Restrictions
An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning control.
•
If the movement amount of each axis exceeds "1073741824 (=2
30
)" when "0:
Composite speed" is set in "
Pr.20
Interpolation speed designation method"
The "Outside linear movement amount range error (error code: 504)" occurs at a
positioning start.
(The maximum movement amount that can be set in "
Da.6 Positioning
address/movement amount" is "1073741824 (=2
30
)".)
Positioning data setting example
[When "3-axis linear interpolation control (ABS linear 3)" is set in positioning data
No. 1 of axis 1]
• Reference axis............. Axis 1
• Interpolation axis.......... Axis 2, Axis3 (The required values are also set in
positioning data No. 1 of axis 2 and axis 3.)
